About DC/OS 1.11

DC/OS 1.11 includes many new capabilities, with a focus on:

  • Managing clusters across multiple clouds. Enterprise
  • Production Kubernetes-as-a-service.
  • Enhanced data security. Enterprise
  • Updated data services.

Provide feedback on the new features and services at:

New Features and Capabilities


  • Multi-region management - Enables a DC/OS Cluster to span multiple datacenters, clouds, and remote branches while providing a unified management and control cluster. View the documentation. Enterprise
  • Linked clusters - A cluster link is a unidirectional relationship between a cluster and another cluster. You add and remove links from one cluster to another cluster using the DC/OS CLI. Once a link is set up, you can easily switch between clusters using the CLI or UI. View the documentation. Enterprise
  • Fault domain awareness - Use fault domain awareness to make your services highly available and to allow for increased capacity when needed. View the documentation. Enterprise
  • Decommission node - Support for permanently decommissioning nodes makes it easier to manage “spot” cloud instances, allowing for immediate task rescheduling.
  • UCR
    • Support for Docker image garbage collection. View the documentation.
    • Support for Docker image pull secrets. Enterprise


  • Edge-LB 1.0. View the documentation Enterprise
  • IPv6 is now supported for Docker containers.
  • Performance improvements to the DC/OS network stack - All networking components (minuteman, navstar, spartan) are aggregated into a single systemd unit called dcos-net. Please read this note to learn more about the re-factoring of the network stack.
  • The configuration parameter dns_forward_zones now takes a list of objects instead of nested lists (DCOS_OSS-1733). View the documentation to understand its usage.

Security Enterprise

  • Secrets Management Service
    • Binary Secret files are now supported
    • Hierarchical access control is now supported.



  • DC/OS Storage Service 0.1 (beta) - DSS users will be able to dynamically create volumes based upon profiles or policies to fine-tune their applications’ storage requirements. This feature leverages the industry-standard Container Storage Interface (CSI) to streamline the development of storage features in DC/OS by Mesosphere and our community and partner ecosystems. View the documentation.Enterprise
  • Pods now support persistent volumes. View the documentation.Beta

Note: Because these storage features are beta in 1.11, they must be explicitly enabled. Beta features are not recommended for production usage, but are a good indication of the direction the project is headed.

Updated DC/OS Data Services

  • TLS encryption for DC/OS Kafka, DC/OS Cassandra, DC/OS Elastic, and DC/OS HDFS is now supported. Enterprise
  • Fault domain awareness for DC/OS Kafka, DC/OS Cassandra, DC/OS Elastic and DC/OS HDFS. Use fault domain awareness to make your services highly available and to allow for increased capacity when needed. Enterprise
  • New API endpoint to pause a node for DC/OS Kafka, DC/OS Cassandra, DC/OS Elastic, and DC/OS HDFS. Use this endpoint to relaunch a node in an idle command state for debugging purposes.
  • New DC/OS Kafka ZooKeeper service. View the documentation.
  • You can now select a DC/OS data service version from a dropdown menu in the DC/OS UI.
  • Improved scalability for all DC/OS data services.

Known Issues

  • DCOS-9751 - Marathon fails to authenticate with Mesos master during disabled -> permissive upgrade.
  • DCOS-18368 - The GUI installer has been retired in 1.11 and will no longer continue to function. It will be decommissioned in 1.12. For details of alternative installation methods, view the documentation.
  • DCOS-19047 - dcos-secrets service is unavailable during upgrade from 1.10.x to 1.11. Enterprise
  • INFINITY-3116 - Deleting failed mnist Tensorflow package never completes.
